Application med ma 27, 1928, Serial No. 248,865,111! in Great BritainSeptember 25, 1926.

This invention relates to apparatus for the distillation of coal andsimilar carbonaceous substances ,and' especially to apparatus forcarrying out a method of distillation in which the distillationiseffected in two stages, the distillation proceeding in the first stageasthe result of heat being applied tothe retort or by internalapplication ofheat through the medium of heated gas, and the secondstage proceeding in a. storage chamber under the heat acquired in'th'efirst stage without the necessary external application ofheat to theretort or chamber within which the second stage is effected. and withoutadditional heat necessarily being applied through the medium of heatedgas. I

The invention further i especially applicable in the distillation ofcoal at low and medium temperatures and for the production of asmokeless" fuel'having a high or moderately high volatile'content, whilethe invention is especially advantageous inapparatus in which the retortorthe like in which the first stage of distillation is effected isseparated by means of adoor from the retort or chamber'or the like inwhich the second stage of distillation is effected.

According to the inventiomin addition to the means rovided at the upperend of the upper reto whereby the gas evolved maybe f .w ithdrawn,-means are also provided whereby as evolved may be withdrawn from thevicinity of the junction between the upper retort or the like and thelower chamber orv the like. The 'gasthus withdrawn by the means adjacent the lower part of the retort is conducted upwards by an outlet pipeand'delivered to the main ascension pipe leading from the upper part ofthe retort at a point behind the antidip valve by which the retort isprotected and isolated during'the discharge. It will be understood thatthe tar which condenses in the auxiliary pipe is allowed to fall into anaddi- 'tional'tar main in which the end of the ascension pipe is sealed.The tar is advantageousdrawing, which represents a sectionalelevation ofa retort and retort setting.

The retort a, in-which 'thefirst stage of the process of distillationrefe'rredto 1s efiected, is provided at the upper end with a charginghood 6 to which is connected a gas outlet conduit pipe 1: for deliveringthe gas into the hydraulic main d by way of the anti-dip valve e. casingor chamber f in which the second stage of the process of distillation iseffected and at the upper end of this retort in the-vicinity of the door9 closing the retort a, gas is with drawn, according to the invention,by a pine or conduit 11. connected with an ascension pipe z servingtoconvey-the gas upwards and to deliver the gas to the ascension eat apoint to the rear of. the anti dip va vc e. The connection of theascension-pipe with the outlet pipe 0 may be providedwith avalve so thatcommunication between the pipes may be broken when desirable. Theascension pipe z extends downwardly into an additional tar main j inwhich the'end of the pipe is sealed by the tar which ismaintained-at aBelow the retort a there is disposed the with a or pockets having coverplates,- to facilitate the use of appliances for clearing the innersurface of the main.

A discharging aperture f is ,provideil adapted to be closed by a coverplate in positi'on immediately opposite to the inclined bottom f of thereceptacle.

It will be understood that the invention is not limited to the detailsof construction hereinbefore described. Thus, in the corn structionillustrated there may also be pro vided a conduit for the withdrawal ofgas from the lower part of the retort'a in the vi cinity of the door 9and connected to the pipe or conduit 12. or to the ascension pipe 2' orsuch a conduit may be; provided alternatively to the pipe or conduit h.

No broad claim is made to the provision of means for withdrawing gasfrom a point adjacent to the dischargedoor of a retort and forintroducing it into the main gas delivery pipe leading from the upperpart of the retort behind the valve controlling communication with thehydraulic main.
